Leviticus 23:19

¹⁷Ye shall bring from your dwelling loaves, as a heave offering, two loaves: they shall be of two tenth portions of fine flour, they shall be baked with leaven of the firstfruits to the Lord.

¹⁸And ye shall bring with the loaves seven unblemished lambs of a year old, and one calf of the herd, and two rams without blemish, and they shall be a whole burnt offering to the Lord: and their meat offerings and their drink offerings shall be a sacrifice, a smell of sweet savor to the Lord.

— Leviticus 23:19 —

²⁰And the priest shall place them with the loaves of the firstfruits an offering before the Lord with the two lambs, they shall be holy to the Lord; they shall belong to the priest that brings them.

²¹And ye shall call this day a convocation: it shall be holy to you; ye shall do no servile work on it: it is a perpetual ordinance throughout your generations in all your habitations.
